Essential details：9907-995 LQ25 Liquid control valve
The main function of the liquid control valve is to control the flow, pressure, temperature and other parameters of the liquid in the pipeline. It converts electrical signals or air signals into mechanical energy through actuators (such as electric, pneumatic or hydraulic actuators) to drive spool or disc movement and achieve precise control of liquid flow.
A hydraulic actuator is a device that uses the pressure of a liquid to produce mechanical motion. Specifically, it is a mechanism that converts hydraulic energy into mechanical energy or other forms of energy. The hydraulic actuator is mainly composed of hydraulic cylinder, hydraulic cylinder and other parts, which uses liquid to generate force and displacement under the pressure of hydraulic cylinder or hydraulic cylinder. When the liquid enters the hydraulic actuator, it will exert a certain pressure to push the hydraulic motor or hydraulic cylinder to move, so as to achieve the control of the mechanical movement.
Hydraulic actuators are often used in control systems that require high precision, high load capacity and high reliability, such as machine tools, industrial robots, automated production lines, etc. Its advantages include high carrying capacity, high precision, good stability and high reliability.
In addition, the working principle of the hydraulic actuator is to use the incompressibility of the liquid and the characteristics of the transfer of pressure, by applying pressure to push the load to move. Therefore, the working process of the hydraulic actuator is usually powered by the hydraulic pump to push the liquid into the closed pipeline of the hydraulic actuator, thus achieving the control of the mechanical movement.

9907-995 LQ25 Liquid control valve
Hydraulic transmission system is a transmission mode that uses liquid as the working medium for energy transfer and control. The system is mainly composed of five parts: power element, executive element, control and adjustment element, auxiliary element and working medium.
A power element, usually a hydraulic pump, whose role is to convert the mechanical energy of the prime mover (such as an electric motor or internal combustion engine) into the pressure energy of the liquid to provide power to the hydraulic system.
Executing elements, such as hydraulic cylinders or hydraulic motors, whose role is to convert the pressure energy of the liquid into mechanical energy to drive the working mechanism to complete various actions. The hydraulic cylinder can achieve linear reciprocating motion, and the hydraulic motor can achieve rotating motion.
Control and regulating elements, such as various valves (pressure valves, flow valves and direction valves, etc.), their role is to adjust and control the pressure, flow and flow direction of the liquid in the hydraulic system according to the need to meet the power and movement requirements of the working mechanism.
Auxiliary components include fuel tanks, oil filters, pipes and connectors, coolers, pressure gauges, etc., which provide the necessary conditions for the normal operation of the hydraulic system and facilitate monitoring and control.
The working medium, that is, the transmission fluid, usually mineral oil, which plays the role of transferring energy, lubrication and cooling in the hydraulic system.
Hydraulic transmission system has many advantages, such as smooth work, responsive, easy to achieve automation, overload protection ability. Therefore, it is widely used in mechanical engineering, automation equipment, Marine and aerospace, metallurgical industry and other fields.
